IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS − This manual contains
important instructions that should be followed during
installation and maintenance of the generator and batter-
ies.
Before operating the generator set (genset), read the
Operator’s Manual and become familiar with it and the
equipment. Safe and efficient operation can be
achieved only if the equipment is properly operated
and maintained. Many accidents are caused by failure
to follow fundamental rules and precautions.
The following symbols, found throughout this manual,
alert you to potentially dangerous conditions to the op-
erator, service personnel, or the equipment.
This symbol warns of immediate
hazards which will result in severe personal in-
jury or death.
WARNING This symbol refers to a hazard or un-
safe practice which can result in severe per-
sonal injury or death.
CAUTION This symbol refers to a hazard or un-
safe practice which can result in personal injury
or product or property damage.
FUEL AND FUMES ARE FLAMMABLE
Fire, explosion, and personal injury or death can result
from improper practices.
• DO NOT fill fuel tanks while engine is running, un-
less tanks are outside the engine compartment.
Fuel contact with hot engine or exhaust is a potential
fire hazard.
• DO NOT permit any flame, cigarette, pilot light,
spark, arcing equipment, or other ignition source
near the generator set or fuel tank.
• Fuel lines must be adequately secured and free of
leaks. Fuel connection at the engine should be
made with an approved flexible line. Do not use zinc
coated or copper fuel lines with diesel fuel.
• Be sure all fuel supplies have a positive shutoff
valve.
• Be sure battery area has been well-ventilated prior
to servicing near it. Lead-acid batteries emit a highly
explosive hydrogen gas that can be ignited by arc-
ing, sparking, smoking, etc.
EXHAUST GASES ARE DEADLY
• Provide an adequate exhaust system to properly
expel discharged gases away from enclosed or
sheltered areas and areas where individuals are
likely to congregate. Visually and audibly inspect
the exhaust daily for leaks per the maintenance
schedule. Make sure that exhaust manifolds are se-
cured and not warped. Do not use exhaust gases to
heat a compartment.
• Be sure the unit is well ventilated.
• Engine exhaust and some of its constituents are
known to the state of California to cause cancer,
birth defects, and other reproductive harm.
MOVING PARTS CAN CAUSE SEVERE
PERSONAL INJURY OR DEATH
• Keep your hands, clothing, and jewelry away from
moving parts.
• Before starting work on the generator set, discon-
nect battery charger from its AC source, then dis-
connect starting batteries, negative (−) cable first.
This will prevent accidental starting.
• Make sure that fasteners on the generator set are
secure. Tighten supports and clamps, keep guards
in position over fans, drive belts, etc.
• Do not wear loose clothing or jewelry in the vicinity of
moving parts, or while working on electrical equip-
ment. Loose clothing and jewelry can become
caught in moving parts.
• If adjustment must be made while the unit is run-
ning, use extreme caution around hot manifolds,
moving parts, etc.
DO NOT OPERATE IN FLAMMABLE AND
EXPLOSIVE ENVIRONMENTS
Flammable vapor can cause an engine to overspeed and
become difficult to stop, resulting in possible fire, explo-
sion, severe personal injury and death. Do not operate a
genset where a flammable vapor environment can be
created by fuel spill, leak, etc., unless the genset is
equipped with an automatic safety device to block the air
intake and stop the engine. The owners and operators of
the genset are solely responsible for operating the gen-
set safely. Contact your authorized Cummins Power
Generation distributor for more information.
5. iv
ELECTRICAL SHOCK CAN CAUSE
SEVERE PERSONAL INJURY OR DEATH
• Remove electric power before removing protective
shields or touching electrical equipment. Use rub-
ber insulative mats placed on dry wood platforms
over floors that are metal or concrete when around
electrical equipment. Do not wear damp clothing
(particularly wet shoes) or allow skin surface to be
damp when handling electrical equipment. Do not
wear jewelry. Jewelry can short out electrical con-
tacts and cause shock or burning.
• Use extreme caution when working on electrical
components. High voltages can cause injury or
death. DO NOT tamper with interlocks.
• Follow all applicable state and local electrical
codes. Have all electrical installations performed by
a qualified licensed electrician. Tag and lock open
switches to avoid accidental closure.
• DO NOT CONNECT GENERATOR SET DI-
RECTLY TO ANY BUILDING ELECTRICAL SYS-
TEM. Hazardous voltages can flow from the gen-
erator set into the utility line. This creates a potential
for electrocution or property damage. Connect only
through an approved isolation switch or an ap-
proved paralleling device.
GENERAL SAFETY PRECAUTIONS
• Coolants under pressure have a higher boiling point
than water. DO NOT open a radiator or heat ex-
changer pressure cap while the engine is running.
Allow the generator set to cool and bleed the system
pressure first.
• Used engine oils have been identified by some state
or federal agencies as causing cancer or reproduc-
tive toxicity. When checking or changing engine oil,
take care not to ingest, breathe the fumes, or con-
tact used oil.
• Keep multi-class ABC fire extinguishers handy.
Class A fires involve ordinary combustible materials
such as wood and cloth; Class B fires, combustible
and flammable liquid fuels and gaseous fuels; Class
C fires, live electrical equipment. (ref. NFPA No. 10).
• Make sure that rags are not left on or near the en-
gine.
• Make sure generator set is mounted in a manner to
prevent combustible materials from accumulating
under the unit.
• Remove all unnecessary grease and oil from the
unit. Accumulated grease and oil can cause over-
heating and engine damage which present a poten-
tial fire hazard.
• Keep the generator set and the surrounding area
clean and free from obstructions. Remove any de-
bris from the set and keep the floor clean and dry.
• Do not work on this equipment when mentally or
physically fatigued, or after consuming any alcohol
or drug that makes the operation of equipment un-
safe.
• Substances in exhaust gases have been identified
by some state or federal agencies as causing can-
cer or reproductive toxicity. Take care not to breath
or ingest or come into contact with exhaust gases.
• Do not store any flammable liquids, such as fuel,
cleaners, oil, etc., near the generator set. A fire or
explosion could result.
• Wear hearing protection when going near an oper-
ating generator set.
• To prevent serious burns, avoid contact with hot
metal parts such as radiator, turbo charger and ex-
haust system.

CONTAINERIZED RENTAL UNITS
POTENTIAL TIPPING PROBLEM
On all containerized rental equipment, there is a potential
problem of having the container tip forward over the land-
ing legs, pulling the axles off the ground when the con-
tainer is fully fueled without a semi-tractor under the king
pin. Jack stands for the front of the container are required
to mitigate this potential problem.
Note: The figure below shows the jack stands and
their placement at the nose of the container.

bus or utility (mains) paralleling applications.
The operating software provides control of the
generator set and its performance characteristics,
and displays performance information on a digital
display panel. It accepts menu-driven control and
setup input from the push button switches on the
front panel.
GENERATOR SET CONTROL FUNCTION
Figure1-1 shows some of the control functions. A
more complete block diagram is provided in Section
3. A system schematic is provided in Section 9.
The PCC monitors frequency from both the
magnetic pick-up (MPU) and the main stator inputs.
The control sends a low power pulse-width
modulated (PWM) signal to the governor output
module, which then sends an amplified signal to the
engine fuel control.
The Bus PT module reduces the bus voltage to
approximately 18 VAC and provides a signal to the
control for reference in synchronizing the generator
set to the system bus.
The external PT/CT module reduces generator
voltage to approximately 18 VAC, and produces a
representative AC voltage from CT output current.
The voltage regulation function sends a low power
PWM signal to the voltage regulator output module,
which then sends an amplified signal to the exciter
stator.
Oil, coolant, and exhaust temperatures are sensed
by variable resistance element sensors. Oil
pressure is sensed by a capacitive element active
sensor.

2. Control Operation
GENERAL
The following describes the function and operation
of the PowerCommand generator set control. All in-
dicators, displays, meters and control switches are
located on the face of the control panel as illustrated
in Figure 2-1.
The PCC control cabinet must be opened only by
technically qualified personnel.
Normally, generator set configuration options are
set at the factory. When a new control is installed on
a generator set or when parts are replaced, the con-
trol must be configured for that generator set with
the use of the “Initial Start Setup” portion of the inter-
nal software. Setup and calibration procedures are
described in Section 5.
The automatic voltage regulator (AVR) and gover-
nor operation characteristic adjustments are also
described in Section 5.
SAFETY CONSIDERATIONS
AC power is present when the set is running. Do not
open the generator output box while the set is run-
ning.
WARNING Contacting high voltage compo-
nents can cause electrocution, resulting in se-
vere personal injury or death. Do not open the
generator output box while the set is running.
Read and observe all WARNINGS and CAU-
TIONS in your generator set manuals.
CAUTION The PCC control cabinet must be
opened only by technically qualified personnel.
Lower level voltages (18 VAC to 24 VDC) are
present in PCC control cabinet. These voltages
can cause electrical shock, resulting in per-
sonal injury.
Even with power removed, improper handling
of components can cause electrostatic dis-
charge and damage to circuit components.
10. 2-2
SEQUENCE OF OPERATION
When the PowerCommand control is in the AUTO
mode, it will cause the generator set to start on re-
ceiving a signal from a remote device. The Power-
Command control will initiate a starter cranking sig-
nal and verify that the engine is rotating. The Power-
Command control will provide sufficient fuel to the
engine to accelerate to start disconnect speed. On
reaching that speed, the control will ramp the gener-
ator set to rated speed and voltage.
On reaching rated speed and voltage, the Power-
Command control checks the system bus voltage. If
no bus voltage is present, it will wait for a pulse from
a remote Master First Start Sensor. On receiving
that pulse, the control will signal the paralleling
breaker to close.
If bus voltage is present, the PowerCommand con-
trol will check for proper phase rotation, adjust the
generator set to the bus voltage and frequency lev-
el, and then synchronize the generator set to the
system bus. When a synchronous condition is
achieved, the control will send a signal to close the
paralleling breaker.
When the paralleling breaker is closed, the genera-
tor set will assume it’s proportional share of the total
load on the system bus.
PCC POWER ON / STANDBY MODE
Standby Mode
In the Standby (sleep) mode (selector switch S5 on
the Digital Board is set to the right and the generator
set is not running), the control’s operating software
is inactive and the LEDs and displays on front panel
are all off.
The operating software is initialized and the front
panel is turned on in response to a run signal or any
one of eight “wake up” inputs from remote sensing
switches.
The wake up signals are:
• Emergency Stop
• Low Coolant Level
• Low Coolant Temperature
• Low Fuel
• Customer Fault Inputs 2 and 3
• Run Selected on Run/Off/Auto Switch
• Remote Start Signal in Auto Mode
• Self Test switch
To activate and view the menu displays, press and
release the Self Test switch. The PCC will initialize
the operating software and permit operation of the
menu display panel. If no menu selections are
made, the power to the control panel will shut down
after 30 seconds.
Power On Mode
In the Power On (awake) mode (selector switch S5
on the Digital Board is set to the left), the PCC will
initialize the operating software and permit opera-
tion of the menu display panel. (See Figure 3-1 for
S5 location.) Power will stay on until switch (S5) is
set to the Standby mode. It is recommended that
switch S5 be left in the Power On mode in all ap-
plications, except those where auxiliary battery
charging is not available.
CAUTION Electrostatic discharge will damage
circuit boards. Always wear a grounding wrist
strap when touching or handling circuit boards
or socket-mounted ICs and when disconnect-
ing or connecting harness connectors.
